Abstract
The utility model discloses a safe and reliable ratchet wheel mechanism which comprises a fixing seat, a ratchet wheel and a rotating shaft, wherein the ratchet wheel is fixedly arranged on the fixing seat through the rotating shaft; a pair of pawls is arranged on the outer side of the ratchet wheel and is arranged on the fixing seat through short shafts; and a fixing cover is arranged on the outer side of the ratchet wheel and is fixed on the fixing seat. The safe and reliable ratchet wheel mechanism has high performance and high torque; clockwise and anticlockwise constraints are avoided; and the mechanism is compact in overall structure and convenient to manufacture, use and operate.
Description
Technical field
The utility model relates to crane gear component technology field, specifically belongs to a kind of safe and reliable ratchet mechanism.
Background technique
Ratchet mechanism is widely used in industry-by-industry, and existing ratchet mechanism design organization is unreasonable.When pulling force increases in use, be easy to produce and jump the tooth tooth phenomenon that even jumps, and will confirm that it is forward with reverse while using.Many ratchets are larger to ratchet elasticity pressure resistance, and ratchet is easier to the stagnant band of ratchet, and convolution, can't work ratchet mechanism simultaneously.
The model utility content
The purpose of this utility model has been to provide a kind of safe and reliable ratchet mechanism, has high-performance, high moment of torsion; Without suitable reverse constraint; Mechanism's compact overall structure, be convenient to manufacture, and uses easy to operate.
The technical solution adopted in the utility model is as follows:
A kind of safe and reliable ratchet mechanism, comprise fixed base, ratchet and rotatingshaft, and described ratchet is installed on fixed base by rotatingshaft, the ratchet outside is provided with a pair of ratchet, ratchet is by the minor axis mounting-fixing base, and the ratchet outside is provided with fixed cover, and fixed cover is fixed on fixed base.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model designs a pair of ratchet and coordinates with ratchet gear, has high-performance, high moment of torsion; Without suitable reverse constraint; Mechanism's compact overall structure, be convenient to manufacture, and uses easy to operate.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, a kind of safe and reliable ratchet mechanism, comprise fixed base 1, ratchet 2 and rotatingshaft 3, ratchet 2 is installed on fixed base 1 by rotatingshaft 3, ratchet 2 outsides are provided with a pair of ratchet 4, ratchet 4 is by minor axis 5 mounting-fixing bases 1, and ratchet 2 outsides are provided with fixed cover 6, and fixed cover 6 is fixed on fixed base 1.
